Counterbalanced crank-shaft.



sihle to move the oounterweght toward amd from the shaft. und Cause the reeezited engagement und disengagement of the ends of these lugs in order to promote 4the heating eli these ends to the welding temperature.

Then 'when one half has been so secured the other half is welded on, and the lugs 26 ou the two halves are welded together simultaneously with the welding togetl'ler of the ends of the lugs 25 and l2. It is possible lo move the Counterweight so as to repeateilly'enuse the engagement and disengagement of the two pairs ol lugs while they :1re lia-ing missed lo the welding Temperature.

lin vi ng described my invention, I claim l. The eomhinnl'iion of a crank Shaft heving two opposilely exlemleil lugs7 and a eminterweighthaving two leg branches which strnddle the purl.. of the crank shaft whereon said lugs are formel-each of Said leg branches having e lng which extends towslril the other,-the ends of the two lugs on the leg branches of the counterweight loemeeseee ing' electrically weldeel te the end-e lah-e two lugs on lie 3i-:ml: shaft.

*2. The Combination of a Creek shaft hamm ing two oppositely emenfled lugs, enel n coiinterweight formed of two halves side by gicleethe 'zicllliecent edges o being -formed with a projecting lug engages with end is electrically Welded te the end of the asseeiziteil lug on the other lmll,-:md seid `wo halves .having reepef3- tively two leg branches which lie on om site sides of the crank shaft and each he; e lug which projects toward the other th ends of Seial lugs heilig respeci l;Y eleetri- (fully welded lo the ends of the lugs 'irmeil en the crank shnlt.

ln testimony whereof, hereunto alla; my Signeture in the presence of two winesses.
